    Question

    A logistic regression analysis was conducted to examine the relationship between bullying (x; higher score is more bullied) and school dropout (y; 0=not; 1=well). The odds of the probability of school dropout for a score x=6 is 0.18, and for a score x=7 it is 0.33. Calculate the odds ratio.

    Formula for the odds ratio:

    θ=π1(1−π1)π2(1−π2)\theta = \frac{\frac{\pi_{1}}{(1-\pi_{1})}}{\frac{\pi_{2}}{(1-\pi_{2})}}


    1. FALSE: 1.16
    2. TRUE: 1.83
    3. FALSE: 0.86
    4. FALSE: 0.55
